While Twitter has already simplified reporting abusive tweets, that’s not enough if you’re facing a very serious threat — you want something that the police can use to get an arrest or restraining order. Thankfully, Twitter has delivered something that might help. A new email option lets you send yourself a copy of a threat report that you can take to law enforcement. While it only provides a basic summary of what happened, it both serves as an official record and helps officers understand what to do if they need private account information to make a bust.

Cautious types will frequently tell you not to rely on cloud storage as your only backup, and a handful of internet denizens have just learned this the hard way. Dropbox has confirmed that a bug in some older versions of its desktop apps deleted the files of some people who turned on Selective Sync, which limits cloud syncing to certain folders. Typically, this would happen after a crash or forced reboot, making a bad problem worse — at least a few users found that they’d lost years’ worth of content through no fault of their own.

Talking to ProPublica, the artist revealed that people were happy to sign away their name, address, driver’s license number, phone number and their mother’s maiden name. As part of the deal, Puno also took pictures of each candidate, and in some cases asked for (and got) fingerprints and the last four digits of what people claimed was their social security number. If anyone asked what she planned to do with the information, the artist pointed to a terms and conditions sheet written in impossibly small text mirroring the sort we routinely ignore when we sign up to a new website.

DARPA’s been spending its money on many, many things other than robots and exoskeletons — including several experiments that seek to determine how we use social media. Apparently, Pentagon’s most adventurous division has quite a number of studies under its Social Media in Strategic Communication (SMISC) program since it was announced in 2011. And thanks to The Guardian (which spotted the details SMISC quietly posted on its website), we now know the projects the agency’s been working on… and they involve not only Facebook, but also Twitter, Reddit, Pinterest, Kickstarter and even Digg. According to the researchers involved, they used only data available to the public, and it doesn’t look like they violated any law. But just like Facebook’s mood experiment, some of these studies might make people a tad uncomfortable.

There have been signs that Americans are leaning more and more on the smartphone as a primary internet device, and nowhere is that clearer than the latest edition of Pew’s Cell Internet Use survey. The research group found that 21 percent of American cellphone owners now get online chiefly through their handset, up from 17 percent last year.
